The Yale Peabody Museum houses more than 11 million specimens and objects in anthropology, botany, zoology, paleontology, entomology, ornithology, and historical scientific instruments in its collections. It is also home to Rudolph F. Zallinger?s murals The Age of Reptiles and The Age of Mammals. Permanent exhibitions include the Hall of Minerals, Earth and Space, the Peabody Dioramas, and the Great Hall of Dinosaurs featuring skeletons from the Museum?s paleontology collections. A number of online exhibits are available, including China?s Feathered Dinosaurs, and In Search of Giant Squid. Professional development is available through the Museum, as well as PDF versions of some curricula. Web pages for the various exhibits have information pages on individual species, collection artifacts, and history of the Museum, and there is a searchable online database for the Peabody collections.
